2 Claims.

This invention relates to improvements in a knock-down display box, and more particularly to a knock-down display box suitable for displaying ornamental textile fabrics having a hinged cover to protect the textile fabric against soiling.

The object of this invention is a knock-down display box of the hinged cover type formed from one single unit blank without any gluing or stapling, and merely by folding and manipulating the blank with the textile fabric inside said blank.

In the drawings comprising three sheets of six (6) figures numbered Figs. 1 to 6 inclusive:

Fig. 1 is a plan view of the one piece unit blank from which the knock-down display box is made.

Figs. 2, 3 and 4 are perspective views showing how the unit blank is manipulated about a unit of textile fabric, to form a display window frame and hinged cover therefor; and

Figs. 5 and 6' are perspective views showing how the hinged cover is manipulated to close the display box and protect the textile fabric contained therein against injury.

Like reference characters designate corre sponding parts throughout the several figures of the drawings.

The blank l0 (Fig. 1), which is formed from one single piece of cardboard or the like, consists essentially of three sections namely: the left hand section for forming a window frame 2|, the central section for fOlming the base member 29, of the display box, and the right hand section for forming the hinged cover member 35.

The left hand section of blank l0 forms a window frame 2| having a window 22; it is creased along all four sides as indicated by the broken lines l4, I6, l9-l9 and 26-26, to provide lines of fold, so that by folding the left hand section inwards along the several broken lines l4, l6, I1, and IS, a window frame 2| (Fig. 2) is formed, said window frame having a side wall I5, terminating in a fold-under flap I I, and end walls |8-|B terminating in individual foldunder flaps 20-2 ll. The left hand section forming window frame 2|, and the central section forming base member 29 are joined together by a strip of cardboard 21 which may be folded along the creases indicated by the dotted lines 24-24 and 26-26 to form a side wall 21 and corner flaps 25-25. Corner flaps 25-25 are separated from end walls |8-|,8 along the cut lines 23-23, so that when the corner flaps are folded inwards along the creases 24-24 (Fig. 2) they form inwardly projecting tongues adapted to cooperate With the fold under flaps 20-20 to lock window frame 2| in its ultimate position.

By folding the blank along both of the crease lines 26-26, the side wall 2'! (Figs. 2 and 3) is formed. One or more elongated slots 28 are formed substantially in alignment with the crease 26 defining the line of merger of side wall 21 and base member 29. Elongated slot(s) 28 cooperate(s) with tongue(s) 31 as hereinafter more fully described.

The central section forming base member 23, and the right hand section forming cover member 35, are joined together by a strip of cardboard, and by folding the blank along the creases indicated by the parallel spaced dotted lines 33-33 and 32-32 the oppositely disposed side wall, and the corner flaps 3|-3| are formed. Corner flaps 3|-3| cooperate with corner flaps 24-24 to lock fold. under flaps 20-20 in place as hereinafter more fully described. One or more elongated slots 30 is formed in the blank along the line of the crease 33 defining the line of merger of base member 29 and the side wall. Similarly one or more elongated slots 34 is formed in the blank along the line of the crease 33 defining the line of merger of the side wall and cover member 35. The elongated slot(s) 34 may be made slightly larger than the elongated slot(s) 33 to afford a degree of play in the hinge formed by slot(s) 34 and tongue(s) |2 when said tongue is brought into registry with said slot as hereinafter more fully described. Cover member 35 is provided with one or more laterally projecting tongues 31 provided with creases 36 and 38 to sub-divide the tongue(s) into a clamping portion and a locking tongue tip 39 which functions as hereinafter more fully described.

Principle of operation.

The blanks H] are placed in a pile in the packing room and the top blank is bent along the various crease lines indicated by the dotted lines |4, |3, 26-26, 33-33, H, I9, 24-24, and 32-32. The textile fabric 4| to be packaged, previously folded so as to lie within the edges of base member 29 is placed upon said base member as shown in dotted outline in Fig. 2. The flaps 25 and 3| are then bent upwards, and Window frame 2| is folded over to the. position shown in Fig. 3 and cover member 35 is folded along the creases 33-33 so that the fold-under flap lies beneath the textile fabric 4| and the tip(s) of the tongue(s) l2 register with and are passed through the slot(s) 34 to form a casing or box having a window frame 2| and a base member 29,

The fold under flaps 2IJ2(| are now'inserted beneath the bottom edges of the corner fiap's 25--3|, 25-3| and beneath the textile fabrics 4| thus completing the casing (Fig. 4). The tongue or tongues |2 (Fig. 4) is or are folded downwards along the crease l6 and then bent inwards along the crease M to engage in the elongated slot or slots 30 to form one or more rigid hinge members for cover member 35, and as the elongated slot or slots 34 are made somewhat larger than the tongue(s) |2 the cover member 35 hinges freely upon the elongated slot(s) 34 and. their associated tongue(s) l2 substantially as shown in Fig. 5. The textile fabric 4| is visibly displayed through the window 22 of window frame 2|, and when the window 22 is sub-divided into two window panes as illustrated in the drawings, a pictorial representation 4!] illustrating both the ornamental design and the manner of using the textile fabric 4| maybe inserted in one window panel leaving the textile fabric to be displayed through the other window panel. By this arrangement the purchaser can examine the actual texture of the textile fabric through the one window panel, and see the design of the textile fabric 4| and the manner of using said textile fabric without the necessity of opening the pack age and unfolding the textile fabric. For ship- -ment and storage purposes and to protect the contents of the package against damage from dust, sunlight, etc., the cover member 35 may be swung about the hinges formed by the tongue(s) l2 to close the box cover, and the tongues 31 (Fig. may be inwardly folded and re-i'olded along the creases 36 and 38 to bring the locking tongue tip(s) 39 into cooperative registry with the elongated slot(s) 28 to clamp and lock cover member 35 in closed position as best shown in Fig. 6. When thus closed the display boxes may be stacked one upon the other and stored without in jury to the textile fabrics contained in the boxes. To display the contents of any selected box it is merely necessary to withdraw it from the stack, release the tongue 31 throw back the cover member 35, thus displaying the contents of the box substantially as illustrated.

To guard against confusion, each distinctive illustration 40, and each textile fabric 4| embodying the design shown in said illustration, carry the same distinctive code number, which code number may be printed upon the illustration 40 and upon a tag attached to the textile fabric 4|.

The blank I0 may be punched in one single operation, out of a sheet of cardboard or other stiff pliable material capable of being folded Without breaking, by means of a suitable creasing and cutting die.
